Filed: 1997-08-28
Abstract: A natural-language speech control method (20) produces a command (34) for controlling the operation of a digital computer (36) from words spoken in a natural-language. An audio signal that represents the spoken words is processed to generate textual digital-computer-data (24). The textual digitalcomputer-data (24) is then processed by a natural-language-syntactic-parser (26) to produce a parsed sentence in a logical form of the command (28). The parsed sentence is then processed by a semantic compiler (32) to generate the command (34) that controls the operation of the digital computer (36). The command (34) is expressed in a natural-language sentence that has an implied second person singular pronoun subject and the verb is active voice present tense. The preferred method uses a principles-and-parameters (P-and-P) Government-and-Binding-based (GB-based) natural-language-syntactic-parser (26) for resolving ambiguous syntactic structures.

Title: Prenatal screening for down's syndrome using hyperglycosylated gonadotropin
Inventor: COLE LAURENCE A
IPC: G01N33/566
Filed: 1997-09-05
Abstract: A prenatal screening method for Down's syndrome involves assaying for hyperglycosylated gonadotropin in biological test samples such as urine, plasma or serum obtained from pregnant women.      Hyperglycosylated gonadotropin comprises a variant population of chorionic gonadotropin, chorionic gonadotropin-free .beta.-subunit, .beta.-core fragment, and/or free .alpha.-subunit exhibiting differences in the carbohydrate content from what is observed in samples obtained from pregnant women carrying normal fetuses.      Qualitative or quantitative observation of differences in the carbohydrate content of the hyperglycosylated gonadotropin population from corresponding control samples containing a normal gonadotropin population, or direct observation of the variant species seen in Down's syndrome, indicates that the woman's fetus has Down's syndrome. Typical screens involve carbohydrate analyses, immunoassays, or combinations of these methods. Some embodiments employ a lectin such as concanavalin A reactive to the carbohydrate moiety; others employ antibodies to at least one hyperglycosylated gonadotropin species.

Abstract: A phase mask for machining optical fibers, which allow easy electron beam drawing of the phase mask whose recessed groove pitch changes according to positions. On the side of a transparent substrate are formed a plurality of repetitive grating-like patterns (A1-A3) of grooves (26) and ridges (27), and the light refracted by the patterns are projected onto an optical fiber to create a grating in the optical fiber by the interference fringes produced by the refracted lights of different orders. The pitch of the grooves increases or decreases linearly or nonlinearly, and the width ratio between the grooves (26) and the ridges (27) is constant. The phase mask is manufactured by arranging a plurality of patterns of grooves (26) and ridges (27) of different pitches and performing the electron beam drawing.

Title: Method of cell surface activation and inhibition
Inventor: GOLDBERG GREGORY I
IPC: C12N9/64
Filed: 1997-09-15
Abstract: Disclosed are methods of cell surface activation and inhibition that involve the interaction of an inhibitor of matrix metalloprotease known as TIMP-2, with the enzyme, gelatinase-A (GelA). Critical to the methods of the invention is the discovery of a unique TIMP-2 binding site on the surface of the C-terminal domain (GelA-CTD) of the enzyme, which has been determined to be Asp656, but which can also include other residues in the Ge1A-CTD domain with which Asp656 forms a contiguous surface, namely Gly651, Phe650, and Tyr636. Identification of this binding site provides a useful target for the screening of MMP inhibitors and for prognosis and treatment of diseases in which MMPs are implicated. Compounds which are candidate MMP inhibitors can be structured to competitively inhibit cell surface activation.

IPC: H02H9/02
Filed: 1998-08-25
Abstract: Un élément résistant à coefficient de température positif (CTP) possède une résistivité qui augmente avec la température. Les disjoncteurs comportants des éléments CTP peuvent assurer une meilleure protection contre les surcharges et les courts-circuits que les disjoncteurs existants. On peut associer ces disjoncteurs à éléments CTP à des circuits de détection de défauts de mise à la terre de manière à activer le disjoncteur dans des conditions de défaut à la terre qui sont moins graves que les conditions de surintensité qui activent normalement le disjoncteur. Un ensemble déclencheur shunt comportant une résistance à coefficient de température positif réduit la puissance nominale requise pour le commutateur de remise à zéro.

Title: Composite carrier assembly having an encapsulated sensor and an associated fabrication method
Inventor: KALAMKAROV ALEXANDER L
IPC: G02B6/36
Filed: 1999-05-27
Abstract: A structure is provided that includes a structural element and a composite carrier assembly associated with the structural element, such as by being embedded therein, wherein the compatible carrier assembly includes a composite carrier and a sensor disposed with the composite carrier. By embedding the composite carrier assembly within a structural element, the sensor, such as a fiber optic sensor, will measure the conditions, such as the strain, temperature or the like, to which at least a portion of the structural element is subjected in a manner which averages the measurements over a distance greater than the predetermined dimensions of the sensor element. In addition, the thermal, mechanical and electrical characteristics of the composite carrier can be precisely tailored, such as to match those characteristics of the structural element in which the composite carrier is to be embedded, so that the composite carrier will be compatible with the host material of the structural element. The composite carrier also provides increased resistance to corrosion and a corresponding longer life for the encapsulated sensor than conventional techniques. A method is also provided for reliably fabricating a composite carrier assembly, including a curved or otherwise non-linear composite carrier assembly.

Title: Breast stabilization devices and methods
Inventor: VETTER JAMES W
IPC: A61B8/08
Filed: 1999-08-30
Abstract: A breast stabilization device includes a substantially rigid outer member and an inner member joined to the outer member. The inner member is configured to conform to the shape of the female breast. An opening is disposed through the outer and inner members, the opening being centered on the nipple/areolar complex of the breast and exposing at least a portion of the areola surrounding the nipple. A rigid rim may surround the periphery of the opening and may rise above the surface of the outer member. The device stabilizes the breast in an uncompressed or slightly expanded state to allow interventional and imaging procedures to be carried out without compressing the breast. The opening allows access to the breast through the areola and the rim allows one or more instruments to be attached thereto. A method of imaging a breast, according to the present invention, includes the steps of placing a generally breast shaped member on the breast, the breast shaped member having one or more imaging port therein; expanding the breast to come into intimate contact with the breast shaped member; and imaging the breast through the imaging port(s). The imaging step may be carried out by directing ultrasonic energy through the port(s).

Abstract: An aerial work platform supported by a riser boom, a telescoping main boom, and a jib boom. Boom movement may be controlled by a platform control module or a ground control module connected to a controller by a controller area network (CAN).  Movement of the platform and the jib boom are limited to a predefined envelope. If an operator attempts to move the platform outside the envelope, the controller automatically retracts the telescoping boom section or automatically levels the jib boom section in order to maintain the platform within the acceptable envelope. Boom section select switches permit the operator to select and move sequentially or simultaneously in different directions. Timers which are part of the system include various interlocks to accomplish safety and power saver features.
